Title: Transformation method of three-dimensional object points onto two-dimensional image points for linear pushbroom images
Inventor: KIM TAE JUNG
IPC: G01C11/02
Filed: 2000-08-25
Abstract: This invention provides a method to transform 3D object points onto 2D image points for linear pushbroom images. The problem is decomposed to the problem of finding sensor line coordinates and the problem of finding sensor column coordinates from linear pushbroom collinearity equations. The procedures to solve the problem are as follows. First, assume an initial value for image line coordinate to be sought for and using this value, calculate the sensor attitude. Next, assume the sensor attitude is constant and calculate a new image line coordinate satisfying linear pushbroom collinearity equations. Next, update the initial value with the image line coordinate calculated and continue the procedures until the difference between an initial value and a new value calculated becomes smaller than a threshold. If the different between an initial value and calculated value is smaller than a threshold, accept the calculated value as the sensor line coordinate. After finding the sensor line coordinate, calculate the sensor column coordinate satisfying linear pushbroom collinearity equations.

Title: Method and apparatus for characterizing multipath interference in circularly polarized signals
Inventor: NEUMANN JANET
IPC: G01S1/00
Filed: 1999-04-27
Abstract: An apparatus for characterizing multipath interference is disclosed. An antenna receives signals that include right-hand circularly polarized (RHCP) transmitted signals, left-hand circularly polarized (LHCP) multipath interference and linearly polarized multipath interference. Right hand signals are preferentially derived from the RHCP signals and left-hand signals are preferentially derived from the LHCP signals. The right-hand signals (multipath attenuated with respect to the line-of-sight signal) and left-hand signals (line-of-sight signal attenuated with respect to the multipath) are separately processed in normal fashion. The resulting range, signal strength and/or carrier phase estimates for right-hand and left-hand signals are then compared to detect the presence of multipath interference and to determine the degree to which it has degraded the readings obtained from the right-hand channel.

Title: Call queuing in a telecommunications network
Inventor: WILLIAMS PHILIP MARK
IPC: H04M3/487
Filed: 1999-06-15
Abstract: In a call queuing arrangement for a network defining a call centre, a service control function (10) maintains a record of all calls held in a queue so that the estimated time of answer of each such call by a server at an answer centre (16) can be announced to the calling customer. Each incoming call results in a call record process (14) being created for that call and, if the period for which a customer may have to wait exceeds a predetermined threshold, the customer is given an opportunity to request to be re-called by the network at a time close to an expected server free time. The customer's place is usually maintained in the queue such that each call joining the queue is answered approximately in turn. The method avoids maintaining a network connection to a calling customer who does not have to hold their line whilst their service request to the server centre is queued.

Title: Twin vane concentric pump
Inventor: STAUDENRAUSCH GEORG
IPC: A22C11/08
Filed: 2001-10-10
Abstract: An apparatus and method for producing predetermined quantities of a meat product, in which the apparatus comprises a twin vane concentric pump with an inlet and an outlet circumferentially spaced from one another, and a pair of independently movable vanes. During operation, one of the vanes is positioned between the inlet and outlet to permit pressurization of meat chunks in a chamber communicating with an outlet opening. The other vane is advanced toward the outlet with the outlet valve closed until a predetermined pressure is reached, at which point the outlet valve is opened to dispense a predetermined quantity of meat product. Similar to single vane meat pumps, the disclosed twin vane pump is capable of handling large meat chunks while causing relatively little damage to the chunks. However, the disclosed twin vane pump provides greater operating efficiency than single vane pumps and also achieves greater pressurization of the meat product than prior art pumps, permitting the meat product to be directly transferred to a stuffing horn without the need for further pressurization.
